ALLOY 0F ZINC.

No Drawing.

To all whom it may concern Be it known that I, THOMAS ABRAHAM BAY-LISS,a subject of the King of England,

residing at Warwick, England, have in-" vented certain new and usefulImprovements in Alloys of Zinc, of which the following is aspecification.

This invention relates to improvements in alloys of zinc containingzinc, aluminium and lead.

According to this invention an alloy of "zincmalun inium and lead, whichshall be malleable, is produced in which the ingredients are present inthe finished alloy in pro-portions between the limits of- Zinc 99.170-99995, Aluminium 0. OO1% 0. 9% Lead 0.01 0.0%

A preferred method of manufacturing the alloy according to the presentinvention is as follows :The zinc and lead are melted in a )ot' orfurnace closed to avoid oxidation. The temperature is raised to andmaintained between350'430 C. tobring the zinc and lead into a moltencondition and, while the zinc andlead are still in a molten condition,the aluminium is then added in a solid or molten state to make thecomposition required. When the aluminium has become evenly disseminatedthroughout the mass and the several components are melted and intimatelymixed together ready for pouring the metal is fluxed with ammoniumchlorid or other suitable flux, skimmed and poured int-omolds to formslabs suitrolling the sheets to the required dimensions and the finalannealing ope-ration follows under similar conditions. The metal thusobtained is extremely tough and strong and is malleable and suitable forstamping and Specification of Letters Patent. Patented Sept. 30, 1913.Application filed May 10, 1912. Serial No. 696,479.

like purposes, or for strip, wire and the like. It may be rolled intolong lengths such as lengths of 100 ft. or 200 ft. or the like suit--able for commercial requirements.

The metals may be present in any proportions within the limits set forthherein and in practice a good mixture is found to be obtained when thevproportions are' Zinc 99. 85% Aluminium 0.1 Lead 0.

What I claim as my invention and desir to secure by Letters Patent is 1.A malleable alloy composed of zinc, aluminium and lead in proportionsbetween the limits of zinc 99.1%99.9%; aluminium doom-0.9%; and leadcom-0.9

2. A malleable alloy containing 99.85% i'lf Sine; 0.1% of aluminium; and0.05% of 3. A method of preparing a malleable alloy of zinc, aluminiumandlead which consists in heating together Zinc and lead to bring theminto a molten condition while the zinc and lead are still ina moltencondi throughout the mass, adding a flux thereto and allowing thealloyto cool and set, thereafter rolling it and subsequently annealin it. i

n testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
